SPECIFICATION forming part of Letters Patent No. 285,315, datedSeptember 18, 1883.

I Application filed June 26,1883. (No model.) 7

To all whom it may concern.-

Be it known that I, EDMOND (3. SMITH, a citizen of the United States,residing at Saugatuck, town of Wcstport, Fairfield county, Connecticut,have invented new and useful Improvements in Knives for Splitting andBeveling Leather, of which the following is a specification. Thisinvention relates to knives for attachment to machines for splitting andbeveling leather, and especially such machines which are described inLetters Patent of the United States granted to Christian Dancel andmyself October 16, 1877, No. 196,197. These knives are curved upward atone end in the plane of the cutting-edge for beveling purposes, and whenin use are clamped on a level bed by means of screws passing throughslots which extend transversely to the cutting-edge. One of these screwsbears on the inner portion of the curved end of the knife, making itnecessary to use a considerable thickness of metal namely, to avoidspringing or cracking-and heretofore the knives have been made of oneand the same thickness throughout; but this form is objectionable onaccount of the labor which it involves to grind the knives and keep themin order.

To overcome this objection .is the object 01 my invention, whichconsists in a knife curved upward at one end in the plane of itscuttingedge, and having a reduced portion extending inward from suchedge, leaving the attaching portion of the knife of the originalthickness of metal.

This invention is illustrated in the accompanying drawings, in whichFigure 1 is an end view, showing the knife previous togrinding. Fig. 2is a like view when the knife has been ground. Fig. 3 is a longitudinalsection, 0 showing also the knifebed. Fig. 4 is a plan or top view.

Similar letters indicate corresponding parts. The letter A designatesthe body of a knife containing my invention. This knife is curved 45upward at one end in the plane of its cutting- -edge, as at B, and isreduced in thickness at and inward from such edge, as at G, and it willbe readily understood that by this reduction the operation of grindingthe knife is ma- 5O terially facilitated, while the article at the sametime is left of suiiicient thickness at the place where it is fastenedto resist the strain or pressure of the screws D without springing orcracking. The screws D serveto fasten the 55 knife to the level bed E bypassing through transverse slots F therein, they being located near theends of the knife, and one bearing on the inner portion of the curvedend, as shown EDMOND 0. SMITH.
